No. Samba does in fact also have the server side of the share management
calls. Jim McDonough added the server side of ShareAdd and ShareDelete a
few months ago (ShareEnum has been there for years). Level 502 is not
implemented (level 2 is though).
See e.g. the function api_RNetShareAdd in smbd/lanman.c

The second part of your questions concerns adding permissions for
individual users for a share (rather than a directory or file object). I
slightly prefer that share permissions are considered a special case of an
access control entry (a different type of ACE) rather than an attribute of
the share since I would probably want to manage the two types of Access
Control Lists (share permissions and permissions on file/directory objects)
with similar syntax. In addition using "shareadd" syntax seems awkward
when lots of user permissions have to be added - since the number or users
or groups who are granted access to a resource can be large and often can't
practically be specified via one long command, it seems likely that using
your syntax would have to call "shareadd" repeatedly on the same resource
(even though the share has already been added). If access control were
to be exposed via net, I would prefer that share permisisions were exposed
via something like "net accessentry add ... resource ... user1=R
type=share" rather than forcefitting it into shareadd (alternatively you
could create a new action on shares like "share grant" or "share
addpermission" but it seems wrong to repetitively readd a share simply to
add more users to the share permissions)
